Cost Analysis for Fire Protection on Structural Members of Residential Steel Building using Fire Engineering Design

In general, fire resistance is determined through the building' uses and stories. But recently a fire engineering design that is done by the calculation of design fires from the fire cell and an evaluation of stabilities for structural behavior at fire condition have applied to almost of countries as a major alternative against a prescriptive fire design. To adopt and utilize the fire engineering design into Korea, at first, we evaluated structural stability of 21st stories steel residential building at fire condition through fire engineering design and secondly the fire protection cost was analyzed with fire engineering design method and the prescriptive one, respectively. No fire protection materials for satisfaction of building law at structural members such as columns and beams were needed and about 90 % of fire protection cost was saved.
